Schrock, Columbus, Ohio, assignor tov The Buckeye Steel Castings Company, Columbus, Ohio ApplicationFebruary 1, 1936, Serial No. 61,991 4 claims.. (C1. 213-60) This invention relates to; improvements in striking castings and coupler carriers for railway use and more especially to a novel application of a coupler carrier iron or coupler wear plate to a striking casting.

My improved arrangement canbe employed on any type of railway car, but it is particularly adapted for use on carsthat are to be placed on dumping machines which turn the car to an almost inverted position to remove the lading.l It is also adapted for use with couplers having a butt end of greater vertical thickness than the shank. l

One of the objects of the invention is toI provide an annular striking casting formed with an integral bottom tie as such a casting has many advantages over the inverted U-shape type which is open at the bottom and employs an entirely separate bottom tie or carrying iron. These ad vantages are` principally addedstrength due to the integral feature, and since the center sills are attached to the striking casting, the sills are prevented from spreading at the bottom by the integral bottom tie. y

Another object of the invention is to provide an arrangement permitting the use of a striking casting having an integral bottom tie with couplers having butt ends of greater depth than the coupler shank, and which has a removable coupler carrier iron or coupler wear plate that rests on the bottom tie and can be applied when the coupler is in position and retained in a manner that prevents its loss or removal even though the car is inverted as when on a car dumper.

A still further object is to provide a structure of this character in which the carrier iron may be retained in position due to its specic construction and to a removable retaining means, the latter being prevented from detaching by the coupler when the latter is in central positions.

With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings:

Fig. 1 is a front elevation of the improved striking casting with the carrier iron, coupler and carrier iron retaining bolt shown in dot and dash lines.

Fig. 2 is a top plan View of the same, partly in section, the section being taken on the line 2-2 of Fig. 1.

Fig. 3 is a verticall sectional view taken on the line 3--3 of Fig. 1.

Figs. 4, 5 and 6 are a top plan view, front elevation and en d view respectively, of the carrier iron.

Fig. 7 is a front elevation partly in transverse vertical section of a fragment of the structure and illustrating the manner of applying the carrying iron to the striking casting after the coupler has been inserted into the latter.

Fig. 8 is a side elevation illustrating the manner of applying the carrier iron to the striker casting, the carrier iron and casting being shown in section and the section being taken on the line 8-8 of Fig. 7.

Fig. 9 is a view similar to Fig. 7 but showing how the carrier is retained in position when the car is inverted on a car dumper.

Fig. 10 is a side elevation of the inverted coupler and a vertical sectional View of the inverted striker and carrier iron, the section being taken on the line III-Ill of Fig. 9.

Referring to the drawings, it will be noted that the striking casting Illa is of annular construction and has a coupler opening I I and an integral bottom tie I2. In Fig. 1, I have indicated the coupler carrier I3, its retaining bolt I 4 and the coupler shank I5. The carrier iron is illustrated in Figs. 4 to 6 inclusive, and it is also preferably formed as a casting having a depending annular skirt I3a that is reinforced by depending ribs I6 and is deepened at the iront and rear to form depending walls I1. The ribs I6 and the ends IBa of the skirt are adapted to' rest on the upper surface of the tie I2 and when in this position the depending walls I'I engage the front and rear surfaces of the tie and tend to retain the carrier in its horizontal position longitudinally of the car.

One of the side walls-of the striking casting is recessed as shown at iI8 to form an overhanging shoulder Isa and the recess is of sufficient height only to accommodate the full height of the carrier I3. The opposite wall of the striking casting is recessed at I9 and this recess is of suicient height to accommodate one end of the carrier iron and the square head Illa of the retaining bolt I4. A shoulder Illb` at the top of the recess I9 acts as an abutment for the bolt head to prevent the latter from turning.

Figs. '7 and 8 show the application and operation of my improved arrangement. These gures show the application or removal of the coupler or carrier. The coupler has a butt end 2I of greater depth than the shank I5 and the coupler is inserted through the opening I I fro-m the front of the striking casting and before the draft key (not shown) is put through its slot 22 in the coupler, the latter is raised until the shank is in contact with the top Illb of the striking casting. The carrier I3 can then be introduced into the opening II between the shank and the bottom tie I2 of the casting. Now the carrier can be lowered so as to bring the same to rest on the tie. At the same time the coupler can be lowered and afterwards it can be shifted toward the left in Fig. 7 to allow sufficient room for the introduction of the retaining bolt I4 through its hole I4a (see Figs. 1 and 2) in the casting. After the retaining bolt is inserted through its hole, a nut I4b is applied and the coupler is returned to its central position (Fig. 7). Obviously the carrier or coupler may be removed by reversing the above procedure.

Figs. 9 and 10 show how the carrier is retained by means of the bolt I4 and the depending side walls I'I of the carrier even though the car is inverted on a car dumper, and it will be noted that the carrier cannot be removed as long as the bolt I4 is in place. Furthermore, the' bolt cannot be removed until the coupler shank is detached or shifted over to one side of the striking casting.

While I have disclosed what I now consider to be a preferred embodiment of theinvention in such manner that the same may be readily understood by those skilled in the art, I am aware that changes may be made in the details disclosed without departing from the spirit of the invention as expressed in the claims.

What I claim and desire to secure by Letters Patent is:

l. In combination, a striking casting having a bottom tie portion, a carrier ironresting on the tie portion and having depending means overlapping opposite side portions of the tie portion, said striking casting having opposite shoulders overhanging the ends of the carrier iron, one of said shoulders being spaced from the tie portion a distance equal to the height of the carrier iron, the other shoulder being spaced a greater` distance from the tie portion, and a head detachably secured to the striking casting and substantially filling the space between the last-mentioned shoulder and one end of the carrier iron.

2. In combination, a striking casting having a bottom tie portion, a carrier iron' resting on the tie portion and having depending means overlapping opposite side portions of the tie portion, said striking casting having opposite shoulders overhanging the ends of the carrier iron, one of said shoulders being spaced from the tie portion a distance equal to the height of the carrier iron, the other shoulder being spaced a greater distance from the tie portion, and a bolt secured to the striking casting and having a head substantially filling the space between the last-mentioned shoulder and a portion of the carrier iron for preventing accidental detachment of the carrier iron.

3. The combination with an annular striking casting having a bottom tie portion and unbroken side walls, of a coupler extending through said casting, a carrier iron for the coupler straddling said tie portion and having depending front and rear walls overlapping opposite sides of said tie portion, and means overhanging the ends of the carrier iron and united with the side walls for preventing said depending walls from disengaging said tie portion, said means including a removable part engageable with one'end portion of the carrier iron and spaced from the upper surface of said tie portion a distance less than the height of said carrier iron.

4. 'I'he combination with an annular striking casting having a bottom tie portion and unbroken side Walls, of a coupler extending through said casting, a carrier iron for the coupler straddling said tie portion and having depending front and rear walls overlapping opposite sides of said tie portion, and means overhanging the ends of the carrier iron and united with the side walls for preventing said depending walls from disengaging said tie portion, said means including a re movable bolt having a head engageable with one end portion of the carrier iron and spaced from the upper surface of said tie portion a distance less than the height of said carrier iron.
